The ESA NEO Coordination Centre (NEOCC) is the operative centre of the SSA-NEO Segment. It is located at ESA's establishment ESRIN (Frascati, Italy). Its aim is to coordinate and contribute to the observation of small Solar System bodies in order to evaluate and monitor the NEO hazard.

This implies the availability of advanced systems for orbit computation and impact monitoring, as well as tools and data needed for performing risk assessment (e.g. follow-up priorities, physical properties database). The SSA-NEO segment operates a set of applications, called the NEO software system. The NEO software system provides information not only to scientific users, but also to other SSA customers and stakeholders, such as governmental institutions, insurance companies, the public at large and the media. The stepwise deployment of the NEO system began with a Precursor Services phase, presently on-going and called 'Phase 2'. The key components of the NEO Precursor Services accessible via the SSA-NEO web portal are:
